Asking prices of active fixed-price listings; configuration (CPU, RAM, SSD) varies.
Used M75q-1 units on eBay US currently start at $70, and the typical asking price is about $194 across 40 fixed-price listings. The spread mostly reflects the CPU fitted (Ryzen 5 PRO 3400GE), RAM and SSD included, and whether a power adapter is in the box.

Plex and Jellyfin transcoding
Works with Jellyfin via VA-API, but AMD's encoder quality and media-server support lag Intel Quick Sync. The table covers every CPU option sold in this chassis. Check which CPU a listing actually has.
| Video engine | H.264 | HEVC 10-bit decode | VP9 | AV1 decode | HEVC encode |
|---|---|---|---|---|---|
| AMD VCN 1.0 | Yes | Yes | Yes | No | Yes |
Plex needs a Plex Pass for hardware transcoding; Jellyfin does not. More detail in our Quick Sync generations guide.
Before you buy one used
- Confirm the exact CPU model in the listing photos or System Information screenshot, not just "Core i5".
- Check that a power adapter of the right wattage is included (65 W or 135 W). Many ex-office units ship without one.
- Ask whether the BIOS is unlocked. Ex-corporate machines sometimes keep an admin password.
- A 2.5" drive needs the caddy and cable, which are often missing when a unit shipped with only an M.2 SSD.

Frequently asked questions
- How much RAM does the M75q-1 support?
- Lenovo's official maximum is 32 GB across 2 DDR4 SODIMM slots at up to 2666 MT/s.
- How many NVMe SSDs can the M75q-1 hold?
- 1 M.2 NVMe slot for storage plus 1 2.5" SATA bay, so up to 2 internal drives.
- Does the M75q-1 have a PCIe slot?
- No. It has no internal PCIe slot.
- Can the M75q-1 use 10GbE or 2.5GbE networking?
- Not internally. It has a 1 GbE Realtek RTL8111EPV; faster networking needs a USB adapter.
- Is the M75q-1 good for Plex or Jellyfin?
- Works with Jellyfin via VA-API, but AMD's encoder quality and media-server support lag Intel Quick Sync. That applies to the best CPU option (Ryzen 5 PRO 3400GE, Radeon Vega 11); check which CPU a listing has.
- How much power does the M75q-1 use at idle?
- about 11 W at the wall at idle, as measured by ServeTheHome (Ryzen 5 PRO 3400GE, 120 V). Your drives, BIOS settings and OS will change this figure.
